The first snowflakes of the season are arriving little earlier than usual in the Chicago area.

The typical date for the season’s first snowflakes is just before Halloween on October 30, but with cold air in place and a weak clipper system moving through the area, snow that has been falling in eastern Iowa and northwest and north central Illinois Tuesday morning is now moving into the Chicago Metro area.

Snow has been reported at Midway Airport. Weather observer Frank Wachowski reported that snow began at Midway Airport at 12:20 p.m. and continued until 12:40 p.m. when it changed to rain. Shortly after 1 p.m., the rain was mixing with and transitioning back to snow as the atmosphere cools.

Through noon, snow has been reported at Aurora and West Chicago with snow also falling at Rockford, Freeport, Rochelle and DeKalb, west to Dubuque and the Quad Cities.

But this snow will not amount to much. With pavement temperatures still warm, the snow is melting on contact with roads and sidewalks, but in areas where it is falling at a heavier rate, the snow is accumulating on grassy areas and colder and elevated surfaces.
